aa6c43644b drm/panel: drop drm_device from drm_panel 
The panel drivers used drm_panel.drm for two purposes:
1) Argument to drm_mode_duplicate()
2) drm->dev was used in error messages

The first usage is replaced with drm_connector.dev
- drm_connector is already connected to a drm_device
  and we have a valid connector

The second usage is replaced with drm_panel.dev
- this makes drivers more consistent in their dev argument
  used for dev_err() and friends

With these replacements there are no more uses of drm_panel.drm,
so it is removed from struct drm_panel.
With this change drm_panel_attach() and drm_panel_detach()
no longer have any use as they are empty functions.

v2:
  - editorial correction in changelog (Laurent)

0ce8ddd8e0 drm/panel: add drm_connector argument to get_modes() 
Today the bridge creates the drm_connector, but that is planned
to be moved to the display drivers.
To facilitate this, update drm_panel_funcs.get_modes() to
take drm_connector as an argument.
All panel drivers implementing get_modes() are updated.

v2:
  - drop accidental change (Laurent)
  - update docs for get_modes (Laurent)

eDP, DSI and DPI). This will be used to initialise the corresponding

Update all panel drivers accordingly. The panel-simple driver only
specifies the type for the known to be LVDS panels, while all other
panels are left as unknown and will be converted on a case-by-case
basis as they all need to be carefully reviewed.

Instead of requiring all drivers to set the dev and funcs fields of
drm_panel manually after calling drm_panel_init(), pass the data as
arguments to the function. This simplifies the panel drivers, and will
help future refactoring when adding new arguments to drm_panel_init().

The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection to verify that no call to
drm_panel_init() with a single argument still exists.

66a4e0ef43 drm/panel: jh057n00900: Move panel DSI init to enable() 
If the panel is wrapped in a panel_bridge it gets prepar()ed before the
upstream DSI bridge which can cause hangs (e.g. with imx-nwl since clocks
are not enabled yet). To avoid this move the panel's first DSI access to
enable() so the upstream bridge can prepare the DSI host controller in
it's pre_enable().

This is also in line with other panel drivers.

c2d7e47ad1 drm: panel-lvds: Spout an error if of_get_display_timing() gives an error 
In the patch ("video: of: display_timing: Don't yell if no timing node
is present") we'll stop spouting an error directly in
of_get_display_timing() if no node is present.  Presumably panel-lvds
should take charge of spouting its own error now.

NOTE: we'll print two errors if the node was present but there were
problems parsing the timing node (one in of_parse_display_timing() and
this new one).  Since this is a fatal error for the driver's probe
(and presumably someone will be debugging), this should be OK.

e362cc6a24 drm/panel: simple: document panel_desc; rename a few functions 
This attempts to address outstanding review feedback from
commit b8a2948fa2 ("drm/panel: simple: Add ability to override typical timing")

Specifically:

* It was requested that I document (in the structure definition) that
  the device tree override had no effect if 'struct drm_display_mode'
  was used in the panel description.  I have provided full Doxygen
  comments for 'struct panel_desc' to accomplish that.
* panel_simple_get_fixed_modes() was thought to be a confusing name,
  so it has been renamed to panel_simple_get_display_modes().
* panel_simple_parse_override_mode() was thought to be better named as
  panel_simple_parse_panel_timing_node().

f8c6bfc612 drm/panel: simple: fix AUO g185han01 horizontal blanking 
The horizontal blanking periods are too short, as the values are
specified for a single LVDS channel. Since this panel is dual LVDS
they need to be doubled. With this change the panel reaches its
nominal vrefresh rate of 60Fps, instead of the 64Fps with the
current wrong blanking.

Philipp Zabel added:
The datasheet specifies 960 active clocks + 40/128/160 clocks blanking
on each of the two LVDS channels (min/typical/max), so doubled this is
now correct.

Convert the AUO b101ean01 from using a fixed mode to specifying a

The AUO b101ean01's datasheet says:
* Vertical blanking min is 12
* Horizontal blanking min is 60
* Pixel clock is between 65.3 MHz and 75 MHz

The goal here is to be able to specify the proper timing in device

kernel is using so that it can used the fixed PLL.

d719cbe9a5 drm/panel: simple: Use display_timing for Innolux n116bge 
Convert the Innolux n116bge from using a fixed mode to specifying a
display timing with min/typ/max values.

Note that the n116bge's datasheet doesn't fit too well into DRM's way
of specifying things.  Specifically the panel's datasheet just
specifies the vertical blanking period and horizontal blanking period
and doesn't break things out.  For now we'll leave everything as a
fixed value but just allow adjusting the pixel clock.  I've added a
comment on what the datasheet claims so someone could later expand
things to fit their needs if they wanted to test other blanking
periods.

The goal here is to be able to specify the panel timings in the device
tree for several rk3288 Chromebooks (like rk3288-veryon-jerry).  These
Chromebooks have all been running in the downstream kernel with the
standard porches and sync lengths but just with a slightly slower
pixel clock because the 76.42 MHz clock is not achievable from the
fixed PLL that was available.  These Chromebooks only achieve a
refresh rate of ~58 Hz.  While it's probable that we could adjust the
timings to achieve 60 Hz it's probably wisest to match what's been
running on these devices all these years.

I'll note that though the upstream kernel has always tried to achieve
76.42 MHz, it has actually been running at 74.25 MHz also since the
video processor is parented off the same fixed PLL.

b8a2948fa2 drm/panel: simple: Add ability to override typical timing 
This patch adds the ability to override the typical display timing for a
given panel. This is useful for devices which have timing constraints
that do not apply across the entire display driver (eg: to avoid
crosstalk between panel and digitizer on certain laptops). The rules are
as follows:

- panel must not specify fixed mode (since the override mode will
  either be the same as the fixed mode, or we'll be unable to
  check the bounds of the overried)
- panel must specify at least one display_timing range which will be
  used to ensure the override mode fits within its bounds

Changes in v2:
 - Parse the full display-timings node (using the native-mode) (Rob)
Changes in v3:
 - No longer parse display-timings subnode, use panel-timing (Rob)
Changes in v4:
 - Don't add mode from timing if override was specified (Thierry)
 - Add warning if timing and fixed mode was specified (Thierry)
 - Don't add fixed mode if timing was specified (Thierry)
 - Refactor/rename a bit to avoid extra indentation from "if" tests
 - i should be unsigned (Thierry)
 - Add annoying WARN_ONs for some cases (Thierry)
 - Simplify 'No display_timing found' handling (Thierry)
 - Rename to panel_simple_parse_override_mode() (Thierry)
